Math help
 

IS anyone here good at this stuff.

i have 3 questions to due. And was wondering if anyone could give me a hand.

1. A circle has x intercepts at A(1,0) and B(5,0) and its center lies on the line y = 4. Determine the equation of this circle?.

2. Find the points of intersection between the circle (x - 3)2+ (y-1)2 = 5 and the line y = 2x -2

3. Find the shortest distance between the point P(6,5) and the line 3x+4y=24.

any help would be awesome.

thank you.

ya ha ha funny ive got that pic and its not really helping.

TTT any help at all? my teacher doesnt really teach but rather talks for 45 then leaves.

do your own homework

this is like gr 12 math? pretty easy stuff man

gr10 maybe gr11 max

you do something similiar to this stuff in grade 12. Think it was in chapter 1

1. determine the radius
2. substitute the equation for the line into the equation for the circle.
3. I dunna kno. Draw it.

what he said

seems like math 11. refer to the formula/equation

its math 12 chapter 2 if i remember... it was dead easy if u remember the equations

for the last question the best thing is use the equation
y=mx+b and draw

first question write out hte equation for a circle and then then plug in the numbers

I think number 2 is math 12..

anywways the last question, change 3x +4y =26 into y =mx+b form . which is y= -3/4 +6 . graph that, and then from the point to the line, use the distance formula.



i think tahts how you do it.

I used to be so good at this stuff, now i have no idea how to do it. It makes me feel old =(

old? i feel dumb! i did this 2 years ago and now i forgot everything! =(

i have grade 12 midterms on tuesday dunno a single thing -_-
LOL...

^ gl with that!~

gettin old too -_-"

get a tutor

read the textbook

^with math, reading the text is pointless. Doing practice questions are more worthy of your time and more useful to your learning.

answer is 4

no, its 5!
